Subject: [PATCH 5/8] cpus: remove TCG-ism from cpu_exit()
Date: Fri, 8 Aug 2025 20:59:02 +0200 [thread overview]
Message-ID: <20250808185905.62776-6-pbonzini@redhat.com> (raw)
In-Reply-To: <20250808185905.62776-1-pbonzini@redhat.com>
Now that TCG has its own kick function, make cpu_exit() do the right kick
for all accelerators.
